FUEL CELL ELECTRODE, AS WELL AS METHOD FOR MANUFACTURING FUEL CELL ELECTRODE, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL

摘要

An electrode for a fuel cell is provided with carbon nanotubes, a fuel cell catalyst carried on the carbon nanotubes, and an ionomer for coating the carbon nanotubes and the fuel cell catalyst. The length (La) and center-to-center pitch (Pa) satisfy the following two formulas: 30 <= La <= 240 and 0.351 × La + 75 <= Pa <= 250, where La [mum] is the length of the carbon nanotubes, and Pa [nm] is the center-to-center pitch of the carbon nanotubes.
